Says Bryan:“I’ve had the Sigma 105 OS macro lens in my kit for over two years and have used it with some frequency. Some of the product images you have been seeing in the recent reviews have been captured with this lens and I have used it for many other needs. While this lens has a little room for improvement (especially with the IS system), the image quality it has reliably delivered has been excellent. I’m comfortable using the Sigma 105mm f/2.8 EX DG OS HSM Macro Lens for important macro projects that come my way.”
